Title: Improvements in change-speed and reversing gear
IPC: F16D31/04
Filed: 1926-12-22
Abstract: 263,806. Krauss, H. Dec. 23, 1925, [Convention date]. Speed-varying mechanism comprises an epicyclic train the relative motion of two members of which is changed by hydraulic braking, the energy expended for which purpose is recovered by a motor. A sum gear 24, Figs. 1 and 2, is connected by a sleeve 6 to a pump wheel 5, which is fast on a driving-shaft 4. Planet gears 25 are carried by a member 26 with a clutch end 31, which is engaged for forward driving by a clutch member 33 slidably feathered on a driven shaft 35. The third epicyclic element or annulus 27 is fast on a floating shaft 28 to which is secured the central gear 8 of a two-element gear pump. The other pump element 7 is carried by the wheel 5. The pump draws oil from a rotary casing 11 in through a port 10 and discharges it through a port 13 into a curved passage 9 in the thickness of the wheel 5, which passage is in itself a reaction member recovering power from the circulated oil. The passage 9 is throttled to vary the speed transmitted by a valve 15 operated through a cam rod 17 and lever 19 from a manually-controlled sleeve 22 slidable on the shaft 4. The speed' of the driven shaft is thus raised gradually from zero to that of the driving- shaft, when the valve 15 is closed and the train turns solid. On increase of load on the shaft 35, oil escapes through a spring-loaded valve 47 so as to reduce the speed automatically. This valve has a turned-back nozzle 48. To effect a singlespeed reversed drive, the clutch 33 is disengaged and the shaft 35 connected to the annulus 27 by a clutch 32, 38, the carrier 26 being held by a brake 29.

Abstract: 1,159,781. Measuring atmospheric radioactivity. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 19, 1966 [July 30, 1965], No. 32450/66. Heading G1A. Uranium in the atmosphere is detected by programme controlled means for sucking samples of air through a filter, and moving the filter to a radiation detector which distinguishes uranium from radon by detecting the 185KeV gamma peak of U235 or the 4À2 to 4À7 MeV alpha peaks of U234, U235 and U238. Samples of air are drawn from a number of pipes in sequence under the control of a programmer actuating electromagnetic valves in fluid lines controlling pneumatic valves in the pipes. The samples are drawn into a measuring head at 10, Fig. 2, by suction applied at 102. The samples fill an annular member 114 in air-tight contact with a filter strip 62 so that radio-active particles in the air are deposited on the strip, as the air passes to outlet 102. The radio-activity which collects on the strip is measured by a scintillation counter 44, the output of which is fed to a pulse height analyzer which counts only pulses due to uranium and ignores pulses due to natural radio-activity (e.g. of radon). After each measurement, cam 90 lifts the annular member 114 clear of the strip 62 and motor 100 winds a fresh length of strip under the scintillator 44.

Abstract: 344,342. Saccharification of cellulose. FOUQUE, H. R., MOREAU, M., and SOC. DES PROCEDES FOUQUE, 6, Rue de Marignan, Paris. Oct. 31, 1929, No. 33175. Convention date, Nov. 6, 1928. [Class 127.] Cellulosic substances such as wood, the husks of cereals &c. are saccharified by the action of acidulated water with the introduction under pressure of oxidization or pyrogenation gases, i.e. non- condensable gases such as are formed in the course of the saccharification by acids, in such manner as to modify the chemical equilibrium in the sense favourable to the production of sugar. Carbon dioxide may be the gas used, and is introduced from below to replace the air in the material. Bodies preventing oxidation, reducing bodies or bodies absorbing oxygen, such as pyrogallic acid, active carbons, thionates, cresols, &c. may be introduced into the mass under treatment. The acidulated water may be used in important quantity relatively to the mass of material and serves to treat successively at decreasing temperatures several batches until its concentration in sugar reaches the required degree. The apparatus used consists of a basket 13 for the wood &c. lowered into a saccharifying vessel 4. The juice formed is sent to a boiler 18 where it is distilled and the volatile products are condensed by a condenser 19 and returned through a reheater 23 to the vessel 4. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of carbon monoxide or oxidation products of all other materials capable of modifying the chemical equilibrium in the saccharification reaction. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a surgical drainage control system
IPC: A61M1/00
Filed: 1966-07-22
Abstract: 1,120,557. Surgical drainage apparatus. H. W. ANDERSEN PRODUCTS Inc. 22 July, 1966 [22 July, 1965], No. 33213/66. Heading A5R. Apparatus for draining a body cavity, e.g. the bladder, comprises a drainage tube 12 for conrection with the cavity, means 20, 26 for elevating a section 14 of the drainage tube above the cavity and an air vent tube 18 connecting the drainage tube, between the cavity and the elevated section 14, with atmosphere at a point higher than the elevated section, the air vent tube providing for a restricted flow of air. The drainage tube 12 is connected to a catheter 10 located in the cavity, e.g. the bladder, and between its ends is supported in the lower end of a plate 20 clamped to a stand 26 so that its height may be adjusted. The air tube 18 communicates with the drainage tube where it is connected with the catheter and extends to the top of the plate 20 where it is open to atmosphere through a restriction provided by a cotton filter 34, a restricted orifice (40) or a valve (42, 44, 45). Alternatively, the bore of the air tube is narrow to restrict the flow of air through it. From the plate the drainage tube extends to a container 16 located below the level of the cavity. In use, body fluid flows along the drainage and air tubes towards the elevated portion 14 thus creating an increasing head of pressure which resists further flow. When the fluid reaches the elevated portion 14 it flows by gravity to the container 16 and creates a syphon which draws fluid from the cavity and the air tube. The syphon is broken when air enters the drainage tube through the air tube. The dimensions of the air tube are such that the syphon will not be broken until the cavity is emptied.

Title: Method and apparatus for the manufacture of glass tubing
IPC: C03B17/04
Filed: 1931-12-01
Abstract: 378,291. Making glass tubing. CORNING GLASS WORKS, Walnut Street, Corning, New York, U.S.A.-(Assignees of Weber, W. C. ; 187, Walnut Street, Corning, New York, U.S.A.) Dec. 1, 1931, No. 33327. Convention date, Dec. 18, 1930. [Class 56.] A method of making glass tubing consists in flowing molten glass from a container in a hollow stream over the crest of an annular curb, and in chilling locally the interior surface of the nascent tube by means of a cooling member within the tube. The outer surface of the tube, which has been in contact with forming-surfaces, is reheated where it emerges from the forming-orifice, and if desired it may then be subjected to artificial cooling. The apparatus comprises a refractory bowl 28 surrounded by an insulating casing 25 which is mounted on ball bearing 16 on a framework 14. A gear ring 17 secured to the casing is engaged by a pinion driven by a motor, so that the bowl 28 can be rotated if desired. A circular aperture 26 is formed in the bottom of the bowl, and it is fitted with a refractory cone or annular curb 32 the upper end of which extends inwards to form a circular orifice 33 through which glass is discharged. A fire-polishing and cooling unit is fitted beneath the cone 32. This unit comprises an annular burner 40, a cylinder 37 through which burnt gases are exhausted by means of suction fan connected to a flue 45, and two cylinders 41, 42 through which water is circulated. Above the bowl, a refractory sleeve 67 is supported by a bracket which is provided with means for adjusting the position of the sleeve vertically. The bracket also supports a pipe 68 that carries at its lower end a conical cooler 70, and water is circulated through this cooler by means of the pipe 68 and an inner pipe 71. A tube 72 extends through the pipe 71 and the cooler and is used for supplying air to the interior of the glass tube as it is formed. A cover 50 extending over the bowl 28 is provided with ports 51 through which gas jets may be directed into the bowl. In use, molten glass 76 flows into the bowl from a forehearth 73 of a furnace, and the bowl is rotated at a constant rate of speed. The glass flows under the edge of the sleeve 67 and thence over the edge 33 of the cone 32 to form a tube 79 which is drawn away by suitable mechanism. The flowing glass is cooled by the proximity of the cooler 70 and by a current of air which is induced by air blown through the tube 72 into the bore of the glass tube 79. The exterior surface of the glass tube, which has made contact with the edge 33 of the cone 32, is first re-melted by the flames from the burner 40 and is then cooled and hardened by the cooling-action of the water flowing through the cylinders 41, 42.
